【Ten Years of Rapid Development in Chemical Processing Equipment】China’s First Complete Set of Equipment for Producing Superheated Steam as a By-product of the Pox Process, 1000–2023

Thread Content

In September 2021, the converter, waste heat boiler, and steam superheater for the methanol production project utilizing coke oven gas, developed and manufactured by Lanshi Heavy Equipment, for Ningxia Baofeng Energy Group Co., Ltd., are under accelerated production and are about to be completed and delivered. Among them, the waste heat boiler features a vertical structure combining flexible thin tube sheets and thick tube sheets, while the heat exchange tubes are spiral coiled tubes, making it difficult to design and manufacture. Focusing on the challenges associated with the manufacturing of equipment internals, the production workshop worked together with technical staff to innovate boldly, optimize the manufacturing processes, and develop implementation plans ； Fully leverage the role of Party branches as strongholds and that of Party members as pioneers to drive workers and the general public to accelerate the manufacturing process. This complete set of equipment utilizes a new technology to address the issue inherent in the traditional pure oxygen non-catalytic conversion process (referred to as POX process), namely the inability to produce superheated steam that can be used as power steam, aside from saturated steam. It is the first set of equipment in China designed to generate superheated steam using this process. Lanshi Heavy Equipment has completed the development of the core equipment for this unit, namely the conversion furnace, waste heat boiler, and steam superheater, which will further enhance the company’s market competitiveness in terms of core equipment for POX waste boiler process units.
